Shaders act as a post-processing layer. After the 3DS renders the game frame, Citra passes that frame through the shader pipeline before displaying it on your screen.

Beyond basic performance, Citra supports post-processing shaders that can radically transform a game's appearance. While the original 3DS had a native resolution of only 400x240 pixels, Citra’s shader engine allows for internal resolution scaling up to 10x. By applying texture filtering and anti-aliasing shaders, jagged edges are smoothed out and flat textures gain new depth. Advanced users often implement custom "Reshade" profiles or internal Citra post-processing filters like FXAA or Anime4K. These shaders can mimic the look of a high-end CRT monitor, enhance colors to look more vibrant on modern OLED screens, or even sharpen lines to give games a hand-drawn, cell-shaded aesthetic.
